Subsea energy storage
Subsea energy storage
Our scalable, modular energy storage system is specially developed for the demanding subsea environment. Using lithium-ion battery technology, Halo provides a reliable, uninterrupted power supply to subsea infrastructure as a temporary, permanent or back-up solution.
A smart solution
Halo is an alternative to umbilical cables, which are prone to failure with age. It’s an easily installable, autonomous power source solution that stands the test of time.
Fully rechargeable, Halo can be integrated with marine renewable energy converters – including our advanced technology, Powerhub – offering low carbon energy systems for subsea infrastructure. Here’s the need-to-know information:
Halo offers an alternative to electrical cables, which are expensive to install and often need repaired or replaced over time. It’s quick to setup, too. And with it, you’ll get a fixed capacity energy supply – plus a range of charge options beyond that, including:
With clean energy solutions, we can reduce the industry’s carbon footprint. Halo uses a modular battery system, designed specifically for powering subsea oil and gas assets. That means it can be implemented into greenfield developments in several ways:
By using a remote power source to monitor subsea wells, you can strip out all other infrastructure leaving just the wellhead and environmental barriers. That means the operator can defer plug and abandonment activities until several assets can be combined in a single campaign – saving time and money. Halo can be used for:
New autonomous underwater vehicles (AUVs) are becoming more commercially available as an alternative to remotely operated vehicles (ROVs). They reduce the reliance on surface vessels, cutting out high costs and fuel dependency, by removing the tether between the vehicle and the surface. But the availability of power can be a challenge over extended periods of residency. That’s where Halo comes in.
Its system is perfect for integration within a subsea garage. Being a modular system, energy capacities of several hundred kWh can be deployed – providing multiple charge cycles for the vehicle and for subsea data processing / transmission to surface. Its variable charge interface also gives the AUV provider a range of options for very long-term deployments, by integrating a power source into the assembly.
It can be configured to buffer the power supply and act as an accumulator, providing a clean and stable power supply for fast charging – much quicker than what’s available directly from the renewable power source.
